Hubby is away to get his Flu/Covid jab..............I'm still not sure he will......that is his choice.
His Friend got his and was as sick as a dog within about 12 hours...and was really sick for about 2 weeks.....

...
I Think he was probably an Anomoly....he'd been on a plane the day before......could be something he picked up there.
Fingers Crossed huh.......?.............
